Please solve the following equation: 2.5(x-3)+1.7x=10.8(x+1.5)Include a step by step how you solved the problem. Your help is much appreciated!

The Given equation is:


2.5(x
- 3) + 1.7x = 10.8(x + 1.5)


Solving the equation means
finding the value of 'x' in this equation.


This can be done
as follows:


Step 1: Open the
brackets


2.5x - 2.5*3 + 1.7x = 10.8x +
10.8*1.5


==> 2.5x - 7.5 + 1.7x = 10.8x +
16.2


Step 2: Transfer all terms of equation containing x to
left hand side and other terms containing only numbers to tight hand side of
equation.


==> 2.5x + 1.7x - 10.8x = 16.2 +
7.5


Please note that when we change the side of any term
its sign gets reversed from + to -, and vice versa.


Step 3:
Add terms on each side of equation.


==> -6.6x =
23.7


Step 4: Divide both side of equation by 6.6. This done
so that the left hand side will become equal to
x.


==> x = 23.7/(-6.6) =
-3.591

Comment on the setting and character of "The Fall of the House of Usher."How does setting act as a character?

Excellent observation, as it identifies how the settings of Poe's stories reflect the characters of their protagonists. Whet...
